Liberals and progressives should be wary of making an issue of deficits, despite the imbalance resulting from the GOP's hypocritical tax cuts. The federal debt, per se, is not a problem. If the government used deficit spending to invest in the nation's future prosperity, as it must and should, there would be no occasion for complaint. What needs to be attacked is our retrogressive tax system, corporate welfare, and military waste and adventurism. Deficit funding -- on efficient and economically competitive infrastructure; health care; lifetime education (not just pre-K to college and technical school, but skill-maintenance and retraining to avoid obsolescence); housing; and guaranteed basic income -- would be a bargain in the long run.
